A plurality of (four in the embodiment) split drums D are arranged at regular intervals along the transport direction P immediately below the linear transport portion on the upper part of the orbiting bar conveyor C. The karawari drum D has a length corresponding to the push transfer bar connecting body K, and a large number of karawari drums D are formed on the outer peripheral edges of a plurality of connecting discs 13 arranged at both ends and the central portion. The bar B ₂ is fixed and supported through at regular intervals. Therefore, the karawari drum D has a configuration in which a large number of karawari bars B ₂ arranged at regular intervals along the circumferential direction are integrally connected by a plurality of connecting discs 13. The drum shaft 14 arranged at the center of the split drum D is supported at both ends through the respective side frames 7, and one end of the drum shaft 14 is used as a drive shaft (not shown) of the drive motor 15. The split drums D are connected and driven and rotated independently of each other.

Each of the split drums D is arranged in a linear transport portion on the upper part of the orbiting bar conveyor C so that the upper portion faces between the front and rear push transport bar connecting bodies K, and the front and rear split drums D of the respective split drums D are arranged. A boiled egg support plate 16 that supports the boiled egg E passing through the portion is arranged in the gap formed between the upper parts. The split drum D is driven and rotated so as to return the boiled egg E transported by the orbiting bar conveyor C in the direction opposite to the transport direction P.

In other words, of the total of three push transfer bars B ₁₁ and B ₁₂ constituting the push transfer bar connecting body K, the rotatable push transfer bar B ₁₁ arranged at the position closest to the conveyor transfer surface F. The bite prevention bar B ₃ is arranged in the gap 31 between the conveyor belt drum D and the split bar B ₂ because the drum D is continuously replaced by the continuous rotation of the split drum D.

Further, as shown in FIG. 7, a part of the bite prevention bar B ₃ is arranged so as to project upward with respect to the conveyor transport surface F of the orbiting bar conveyor C. At both ends of the boiled egg support plate 16 in the longitudinal direction (width direction in the arranged state), screws 18 are attached to the horizontal fixing plate portions 8 (see FIG. 2) horizontally arranged inside the opposing frame 7. It is fixed through. In addition, in FIGS. 1 and 3, 21 and 22 indicate the carry-in and carry-out shoots for carrying in and out the boiled eggs E which have been split and split.

In the orbiting bar conveyor C, the boiled egg E continuously supplied from the carry-in chute 21 to the orbiting bar conveyor C by the driving rotation of the chain gear 5 on the downstream side causes the upper linear transport portion to travel in the transport direction P. After being separated and accommodated between the front and rear push-conveyor bar connecting bodies K, the direction connecting the blunt end portion and the sharp end portion faces the lateral direction Q or a direction similar thereto. It is conveyed on the conveyor transfer surface F. When the portion of the split drum D is reached from each, the split drum D is driven and rotated so as to return the boiled egg E being transported in the direction opposite to the transport direction P, so that many of the many boiled eggs E are In the above posture, the action of the split bar B ₂ continuously colliding with each of the split drums D while being pressed against the rotatable push-conveying bar B ₁₁ and the bite prevention bar B ₃ is exerted from each. By repeating in the split drum D, the boiled egg E is split. The boiled egg E transported by the orbiting bar conveyor C often has the above-mentioned posture, but the posture may be changed by the collision action of the split bar B ₂ during the transport. Immediately after the collision by bar B _2, it is often returned to the most stable attitude.

Here, the press carrier bar B _11, which is located closest to the conveyor transport surface F of the conveyor push the total of three constituting the press carrier bar connecting body K bar B _11, B _12, the press carrier bar B _{Since the 11} is continuously replaced, the bite prevention bar B ₃ arranged between the split bar B ₂ and the split bar B ₂ has a rotatable structure. For this reason, the boiled egg E that constitutes the Kara-wari drum D and is pressed against the bite prevention bar B ₃ and the push-and-convey bar B ₁₁ by the Kara-wari bar B ₂ that is continuously replaced in the rotation direction The rotational sliding resistance becomes smaller, the rotation becomes easier, and the rotational load of the boiled egg E on each of the bars B ₃ and B ₁₁ becomes smaller. As a result, the rotation of the boiled egg E that collides with each of the bars B ₃ and B ₁₁ becomes smooth, and in addition to preventing the main body of the boiled egg E from biting into the gap 31, each bar The chances of the boiled egg E colliding with B ₁₁ , B ₂ , and B ₃ increase, and the boiled egg E is surely split. In addition, since the rotatable bite prevention bar B ₃ is arranged in the gap (space) between the push and transport bar B ₁₁ and the split bar B _{2 because} it is continuously replaced, it is boiled as in the conventional structure. A part of the main body of the egg E bites into the gap 31 and is deformed, so that the shape can be effectively prevented from being deformed.

Further, in the above embodiment, since the bite prevention bar B ₃ has a rotatable structure, there is an effect that the rotational load of the boiled egg E can be reduced, but the bite prevention bar B ₃ has a fixed arrangement structure. Even so, it is possible to prevent the boiled egg E from biting into the gap 31.

Further, in the above embodiment, the bite prevention bar B ₃ and each push transfer bar B ₁₁ closest to the conveyor transfer surface F are rotatably supported, and the rotation of the split drum D causes the rotation along the rotation direction. It has the effect of minimizing the rotational load on each bar B ₃ and B ₁₁ of the boiled egg E that is rotationally urged by the split bar B ₂ that is continuously replaced, but only the bite prevention bar B ₃ can be rotated. In terms of structure, the push transfer bar B ₁₁ closest to the conveyor transfer surface F may have a non-rotating structure as in the conventional structure.
